The Extreme 11 I have is a Gen1 x79 board. they don't have a great reputation. (it's currently in Gen3 x99)
I think it has a faulty/failing Plex chip. I never could get four cards running right in it with a 4930k. Runs great with two cards though.
It was my first Intel since my dual Pentium II slot 1 days. (decades ago on a Micronics dual slot 1 BX100 MB) Been an AMD guy for a great many years since.
I'm pretty disheartened with Intel at this point especially with the pins on the MB, who's bright idea was that? I've built them for other people, but from my vision and experience, I've had more problems keeping peoples Intel machines running than I ever have had with AMD. When they originally shipped these boards they weren't even in an antistatic/mag bag, they just zip tied them to the foam packing!. (I shoulda got a clue from that)
For myself, strictly AMD. out of the four Extreme 11's/4930k's I bought, I only managed to get one working. Newegg refused to RMA one of the boards and Asrock refused also claiming that I bent the pins. Installer damage is not covered. I didn't bend no damned pins.
So I ate one of the boards and ran one and returned the rest. (then went back to AMD and the 8350)
Will never buy another Asrock product. (I'm solidly behind MSI)
Anyway I'm getting ready to sell the Extreme 11/4930k combo on ebay, will do a BIN for 450.00/best offer. (see if there is any interest, I don't even want to pull the processor out of it, I might screw up the MB pins)
Intel inside give me the willies....
Never ran an nvidea 780a board, FX790's were more to my liking. (with a Phenom II X4) Vishera's generally require an AM3+ socket board. (usually a 990FX, my general rule of thumb and after 300+ builds on the 990FX platform, I would say a reliable one)Edited by Egilman - 2/3/16 at 2:15pm
